All
• Use appropriate procedures and tools, including ICT
• Describe integer sequences; generate terms of a simple sequence, given a rule (e.g. finding a term from the previous term, finding a term given its position in the sequence)
• Generate sequences from patterns or practical contexts and describe the general term in simple cases

Most

• Select appropriate procedures and tools, including ICT
• Use correct syntax when using ICT
• Generate terms of a linear sequence using term-to-term and position-to-term definitions of the sequence, on paper and using a spreadsheet or graphical calculator
• Use linear expressions to describe the nth term of a simple arithmetic sequence, justifying its form by referring to the activity or practical context from which it was generated
